4.1.3. Volumetric Discharge

Try these first

1. 1.

   Define volumetric discharge in basic terms.

   Hint

   Think about how flow rate relates to area and velocity.

2. 2.

   What does the mass conservation equation state?

   Hint

   Consider a system where fluid is entering and exiting.

3. 3.

   What does volumetric discharge represent?

   • Mass per unit area
   • Volume per unit time
   • Pressure

   Hint

   Think about how fluids flow.

4. 4.

   True or False: Inflow must equal outflow in an incompressible flow.

   • True
   • False

   Hint

   Remember the balance of fluid entering and exiting.

5. 5.

   A pipe has a diameter of 0.1 m and carries water at a speed of 2 m/s. Calculate the volumetric flow rate and find the force exerted on a valve which stops the flow.

   Hint

   Consider how you relate momentum changes with forces acting at outlets.

6. 6.

   A jet of water strikes a flat plate at a speed of 10 m/s and has a cross-sectional area of 0.01 m². Calculate the force exerted when it hits the plate.

   Hint

   Use the relationship between flow rate and forces acting.
